  1. 16. A remote-sensing approach to studying drought resistance in Swedish old-growth and production forests

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Julika Wolf; [2020]
    Nyckelord :Physical Geography and Ecosystem Analysis; drought impacts; old-growth forests; forest management; remote sensing; Earth and Environmental Sciences;

    Sammanfattning : Boreal forest ecosystems are predicted to experience hotter and drier summers due to climate change, leading to more frequently reduced soil water availability and an increased risk of droughts, as was already the case in Northern Europe during the severe summer drought of 2018. Prolonged water stress in forest ecosystems can lead to impacts ranging from reduced photosynthesis to forest dieback. LÄS MER

  3. 17. An agroecological perspective for improving drought tolerance of wheat cultivars for Sweden

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Marwan Mohammed Ismael Alamrani; [2020]
    Nyckelord :wheat production; drought stress; phenotyping and new technologies;

    Sammanfattning : Drought stress is one of the major abiotic stresses that cause losses in cereal production around the world. Drought stress causes several morphological, physiological, biochemical and molecular transformations in plants. LÄS MER

  4. 18. Hur påverkade den torra sommaren 2018 bottenfaunans artdiversitet, individtäthet och den ekologiska statusen i vattendrag i södra Sverige?

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Isabella Blomlöf; [2020]
    Nyckelord :ASPT; Benthos; Density; Diversity; Drought; Ecological status; MISA; Streams; ASPT; Bottenfauna; Diversitet; Ekologisk status; MISA; Torka; Täthet; Vattendrag;

    Sammanfattning : During the summer of 2018 Northern Europe, including Sweden, was affected by extremely high temperature and drought. The drought affected the society and environment that we and other organisms live in. Streams are one of the ecosystems sensible to these conditions. Long periods of drought may affect the waterflow or cause desiccation of streams. LÄS MER

  5. 19. Risk, Resilience and Insurance in Sudanese Pastoralism

    Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Författare :Alla Safieldin; [2019]
    Nyckelord :Climate change adaptation; Disaster risk management; Drought; Index-based livestock insurance; Pastoralism; Risk; Resilience; Sudan; Earth and Environmental Sciences;

    Sammanfattning : The nomadic pastoralists of the Sahel are often identified as a group at the frontline of global climate change. Their existence in arid and semi-arid regions and their reliance on seasonal rainfall are among the factors that contribute to their vulnerability to drought and climate shocks. LÄS MER

  7. 20. Forest Reaction to the 2018 Drought : comparing the Hyltemossa and Rumperöd Forests

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Emily Delin; [2019]
    Nyckelord :forest; drought; forest management; ecosystem flux; physical geography and ecosystem science; Earth and Environmental Sciences;

    Sammanfattning : This paper analyzes the reactions of two forests, located in the same region, to drought conditions that occurred in 2018. Both locations experienced similar conditions including higher temperature and less precipitation than the previous four years. LÄS MER
